There is an interesting
There is an interesting look at the relationship between the two friends, their separate lives and the events that occurred before their deaths, whereas the film is about the relationship between the two men and the events that happened after their deaths, that are presented in the film. Also, it's a good movie to watch and if you haven't seen it yet, you can watch it right now.
There is an interesting twist at the end. There is a hint of a sexual dimension to the story, in the way that the title suggests, but I found it more likely that the film is being compared to other cult films.
